Los Che have been left with a mountain to climb in order to make it to Turin, thanks in part to a contentious opening goal at the Ramon Sanchez PizjuanValencia coach Juan Antonio Pizzi has slammed the officials after his side's 2-0 Europa League semifinal loss to Sevilla on Thursday.
The Andalusians took the lead thanks to a controversial goal from Stephane Mbia, which was closely followed by a second from Carlos Bacca.
The Argentine was livid with the decision not to flag the Cameroonian midfielder offside as he opened the scoring from close range.
"It was obvious," he told Cuatro when asked about the goal. "The action of the first goal changed the entire game.
"We need more clarification [on such contentious calls]. We need the evidence of [television] images.
"I'm sad because we gave it all yet we left with nothing. They took the lead and we didn't. But I'm proud of how we played in the field.
"Logically, after a defeat like this you always leave with a feeling of sadness. Today's result doesn't reflect what happened on the pitch."
